The "Hotcake" Wet Film Thickness Gauge is a Paint Thickness Gauge that makes measurements on slightly curved or irregular surfaces. The gauge is versatile as it can measure with a relatively small footprint, wet paints on objects of practically any size and shape.

Measurement Principle - Paint failures can start anywhere, but most frequently occur in corners and edges where the paint film is either too thin or too thick. When the paint film is too thin, coverage is poor, and loss of hiding and essential protective characteristics are the result. When the paint film is too thick it tends to sag and crack, defacing the film and causing premature paint failure. Overall estimates of film thicknesses are readily made, but are often inaccurate. Such errors can result in waste of time, money, and materials, as the job has to be done over.
However, the wet film thickness can readily be measured with the “HOTCAKE” paint thickness gauge. Such measurements are important to check the rate of paint application, thereby controlling the ultimate film thickness, and assuring a proper paint job. This wet film thickness gauge in all likelihood will pay for itself on just one job. The price of the gauge is nominal.
